Laravel 日志中的错误没有告诉我需要修复什么

Question

我几乎每天都在 Laravel 日志中收到错误消息，但错误消息并没有告诉我是我的哪个视图或控制器导致了错误。这是一个 FormRequest.php 错误，所以我知道这是一个表单验证错误。问题是我的网站有数百个表单，所以我不知道我需要修复哪个脚本才能使错误消失。

这正是我遇到的错误。如您所见，堆栈跟踪仅提及供应商文件。它没有列出我自己的任何脚本，也没有给出任何修复建议。

请注意：我不是在寻求解决“传递给 Illuminate\Validation\Factory::make() 的参数 2 必须是数组类型，给定为 null”的解决方案。我要求我的代码中的错误所在，以便我可以修复它。

Answer 1

我猜你的应用中某处正在使用 FormRequest 和 rules() 方法 return a null.

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        // your validation rules
    ];
}

rules 方法需要 return 一个数组。
